Let's divide 723310 by 2
The aim is to understand the frequency of 2 in 723310.

Moving on to step 1:
If we divide 7 by 2, we get 3 and a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtract 6 from 7 to get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 2

Let's proceed to step 2:
12 divided by 2 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we take 12 away from 12, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

Moving on to step 3:
2 goes into 3 1 times with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 361.0
If we subtract 2 from 3, we get 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 2

Step 4:
2 can be fit into 13 6 times, resulting in a remainder of 1.
The next digit of our result is 6. 
Result so far: 3616.0
Deduct 12 from 13 and we're left with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Let's proceed to step 5:
11 divided by 2 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 36165.0
If we take 10 away from 11, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

On to step 6:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 361655.0
If we take 10 away from 10, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 361655.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 361655.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 361655.0 and a remainder of 0.0.
